# API and Rules

You can set icons/colors from your editor scripts:

```csharp
VHierarchy.VHierarchy.SetIcon(cameraGameObject, iconName: "Camera Icon");

VHierarchy.VHierarchy.SetColor(cameraGameObject, colorIndex: 2);

```

Also you can define rules to set icons/colors automatically:

```csharp
[VHierarchy.Rule]
static void Rule(VHierarchy.ObjectInfo objectInfo)
{
    if (objectInfo.gameObject.GetComponent<Camera>())
    {
        objectInfo.icon = "Camera Icon";
        objectInfo.color = 2;
    }
}
```

Here's an [example script](https://gist.github.com/kubacho/7cf8bc607b3dd1be81ed0c61edac66fb) with a rule that implements automatic icons based on first component
